PURPOSE:To simplify the structure by rotating the output shaft on a cam shaft side of an injection pump and a control rod, and changing the phase between an input toothed wheel connected to a crakshaft and the output shaft so as to adjust the injection time appropriately. CONSTITUTION:When an engine is operated, an input toothed wheel 11 is rotated through a toothed wheel 28. Since the rotation of a control rod 16 is restrained by means of an actuator 21, a pair of differential pinions 18, 19 revolve to rotate an output shaft 14, and a cam shaft of an injection pump is further rotated. Since toothed wheels 11 and 28 are in the ratio of one to two regarding to the numbers of their teeth, the rotation speed of the output shaft 14 is decelerated to a half of the rotation speed for the input toothed wheel 11. When the actuator 21 is driven in this condition, the control rod 16 is rotated, and phase between the input toothed wheel 11 and the output shaft 14 is changed through the differential pinions 18, 19 while the fuel injection time being adjusted. |
